The Centraco incineration unit has several preparation workshops located upstream of the incinerator.
Solid waste is received in drums, monitored via X-ray, and routed to the different workshops, depending on its characteristics. Liquid waste is received in drums or tanks, and transferred to intermediate storage tanks specific to each type of liquid. Depending on the type and conditioning of the waste, the pre-incineration phase enables waste to be routed via different processes in order to prepare batches for incineration.
The Centraco incineration unit is equipped with a static furnace, enabling combustible radioactive waste to be incinerated safely (in terms of both nuclear safety and industrial safety).
Incineration residues, mainly comprising ash and clinker, are conditioned in 400-litre drums. The final packages from incineration are compliant with ANDRA requirements. The residues are reassigned to the respective stakeholders in proportion to the weight and activity of the incoming waste.
Note that there is no reassignment of packages in the case of incinerated liquid waste.
The incineration unit enables waste volumes to be reduced by a factor of between ten and twenty, and also allows precise physical/chemical and radiological characterisation of packages sent for storage.
Cyclife France is authorised to treat low-level radioactive waste from foreign producers at the Centraco site, under nuclear safety conditions that are identical to those applicable to the treatment of French waste. Final waste is returned to the producing country after treatment.
